Oct 18, 2011I am facing an isssues with 7609 for LAN switching , based on LAN (VRRP/HSRP) feature.Actually we are having ES+ cards (on 7609) and we are using multiple groups(say 350 vrrp groups) running on the router . the routers are connected as router 1>>> mux(which is working as switches)>>> router2
my questing are
1. does their will be "multicast packets" (for VRRP/HSRP group) "from backup router to Master router", when in stable state( ie when Master and backup are already chosen) , or the packet from backup to master should be unicast.I know for sure, the packet from master to back is multicast packets denstination to Multicast IP packet and To MAC address.I am not sure but I think from backup to master it should be multicast
2. what is frequency of these packets( from backup to master)
3. As i have multiper group on a single interface ( we are using q-in-q), when the connectivity from router's is broken, then does all the groups will muticast their active roll in the lan sengment "at once" or it will be in a groups say 100 groups at once, and after few ms few 100's and sone ( as is on OSPF or RIP)
we are in between troubleshooting I hope we get the ans( Actul problem we are seeing in the router's that we have 2 ports on active routers and 2 ports on standby router , but we are not seeing muticast on 1 port on standby router where as all other 3 ports are seeing multicast packets) [code]

Sep 18, 2012I'm trying to set up a 2951 with a 24 port switch module. I want the ports to act similiarly to the ports on an 881 router - where I assign the VLANs on the router and I set the VLANs to the switchport interfaces.I would like to be able to create the VLANs on the router portion of the 2951 and then, enter the switch module and configure the Ports to the VLANs but, how do I logically connect router to the switch? Is it an internal logical interface - meaning how are the VLANs getting from the router to the switch?

However, I want to know whether there's any software (preferred web based application which allows me to change the gateway from line #1 to line #2 for all 70 computers instead of having to go to each workstation to update the gateway).
Cisco Switching/Routing :: 3560E - HSRP Gateway Failover And Routing Table
Nov 12, 2012We have two Cisco 3560E layer 3 switches at the core of our network. The switches are configured as an HSRP pair and the clients on our network point to the HSRP address as their default gateway. So if CORE-A dies, then CORE-B will pick up the address and the default route for the clients will continue to be available.We also need to specify a few static routes on the core switch to allow us to get to specific networks. Is there a way to do this so that the routes failover in the same way that the default gateway does?
View 2 Replies View RelatedCisco Switching/Routing :: 2921 Process Of Switching Infrastructure Of Firewalls / VPNs
Jul 4, 2012We are in the process of switching our infrastructure of our routing/firewalls/vpns over to cisco. We are switching our first location and one of the issues I'm struggling with is windows authentication pass-through for internally hosted web pages. Meaning, user inside our network has the 2921 as their default gateway, they try to access a web page that is hosted on the internal network but is secured with windows authentication. In the past, because they are logged into the domain internally, the website authenticates and loads. After switching to the Cisco, it asks for a password even though they are logged in.
Because its the web server that actually authenticates I'm not sure why the router isn't allowing that to happen, but I can't think of anything else that could be causing this behavior.

i know if use two l3 switches (instead of routers) and connect to a LAN switch then we need a back to back connection between the L3 switches
also can we use hsrp on vss on 6500?

if the above design is acceptable how does the routers know which one is active and which one is standby ? if we need a direct connection between two routers they have to be on a seperate subnet and routers dont allow broadcasts - so how will hsrp work on routers ?

Cisco Switching/Routing :: 3560x / HSRP On LAN And WAN Interface?
May 9, 2012I currently use L3 switches as edge routers to my WAN. I want to use a pair of 3560x switches with IPbase to provide a failover path to my WAN using HSRP at one location but had some problems testing the configuration. My plan is use a virtual address on the LAN interface (VLANx which port gi0/1 accesses) and the WAN interface (VLANy which port gi0/24 accesses). I want switch 1 to be primary since it will have an IPS attached to it, and switch 2 will be backup and used only when switch 1 or the IPS requires maintenance. On both the LAN and WAN sides there is no advanced routing going on, the various hosts just depend on the availability of their respective default gateways, so HSRP should be sufficient to provide a failover in either direction.
In my testing I got 1 or the other link to fail over but not the entire switch. What should my config look like to achieve failover of the entire switch in the event 1 or the other interface goes down, and fail back when the primary links are again available?

View 3 Replies View RelatedCisco Switching/Routing :: 6500 - HSRP Is Instable
Apr 14, 2013n our datacenter we've implemented HSRP on 2 6500's for redundancy purposes. Both switches are connected via a trunk. When an interface is administratively brought up, HSRP becomes instable. Below some selective logging:
12:58:01.759 CET: %HSRP-5-STATECHANGE: Vlan32 Grp 32 state Standby -> Active12:58:01.919 CET: %HSRP-5-STATECHANGE: Vlan21 Grp 21 state Standby -> Active12:58:02.031 CET: %HSRP-5-STATECHANGE: Vlan42 Grp 42 state Standby -> Active12:58:02.031 CET: %HSRP-5-STATECHANGE: Vlan18 Grp 18 state Standby -> Active12:58:02.223 CET: %HSRP-5-STATECHANGE: Vlan4 Grp 4 state Standby -> Active
Basically what happens, is that both switches becomes active and thus are forwarding traffic. After a few seconds all is back to normal. It seems they are missing each others "hello messages", so the state change is in this case normal outcome. What I can't figure out', is the root cause. Since it is triggered by bringing up an random interface configured as a dot1q trunk, I'm thinking of STP limits. But the limitations I found are 10.000 active STP logical ports and 1800 virtual ports per slot. In my case this is 2591 logical ports and all the virtual ports per slot are below 1800. This suggest the switch is capable of running this set-up without a problem.
Some extra information:-Sup 720 10GE-Version 12.2(33)SXH2a-No Vss used-No drops on trunked interfaces between the 2 core switches-83 standby groups (max256)

Cisco Switching/Routing :: HP C7000 / Nexus 5K - Locking Down HSRP ARP / MAC?
Mar 6, 2013Had a Sev 1 issue today. We have a bunch of Nexus 5ks connecting to some HP C7000 Chassis for the use of Virual environments. Engineers build and tear down servers during the day, however today, an engineer configured a virtual machine accidently with its IP address as the default gateway. Each pair of nexus switches has one physical SVI per vlan and a HSRP address for the vlan. Of course this engineer configuring the server IP address as the HSRP address killed the vlan... which lead me onto think... are they are tried and tested techniques to protect this from happening on the switch. Enforcing the ARP/MAC of the HSRP address and not allowing it to change or any other device to change it?

May 17, 2012I have a paif of nexus 5548 configured VPC using the mgmt interface as heartbeat and 2x10G as peerlink. Peer-gateway is also configure on the vpc domain. I have 2 FEX straight thru connection to each Nexus'es. Created 2 VPC and both are up and no suspended vlans. Allowed VLANs in peerlink is 10,20,30,40 and 50. I configure SVI for VLAN 10 on both nexus 10.10.10.100/24 and 10.10.10.101/24 respectively. The problem is when I create HSRP on this VLAN 10 (vip 10.10.10.88), the hello packets are not heard by both nexus, thus both Nexus are acting as active with unknown standby. I can ping both vlan 10 from each Nexus. I tried deleting and putting back the config but no luck.I tried creating another SVI vlan 20 on both nexus and form hsrp, result is same as in vlan 10. I am running version 5.1 release on both nexus.

Feb 21, 2013I have a few old 2600 routers (2621, different IOS's) which I'm now replacing for new one's from the 2900 series (2901, Version 15.1(4)M4).In my configuration I have two IP addresses in my LAN interface and I have HSRP configured within the secondary IP subnet range. It would be something like this:
interface GigabitEthernet0/1
ip address 172.x.x.x x.x.x.x secondary
ip address 10.z.z.z z.z.z.z
[Code].....
Now, in the new 2900 routers, my interface configuration hasn't changed however I can see that the hello packets are now sent with the source within the respective HSRP IP subnet so I had to edit my acl for that:
permit udp 172.x.x.x x.x.x.x host 224.0.0.2 eq 1985
Is there a way I can force the HSRP to work as it previously did in the old IOS's?
